Subject: [PATCH] fix(task): fix closure compatibility issue with
 ZoneDelegate._updateTaskCount (#878)

onHasTask wasn't getting triggerred for the Angular Zone for setTimeout
when the application was closure compiled. This was causing errors with
Protractor not being able to wait for a closure compiled application using setTimeout.
